Physicists demonstrate first metro-area quantum computer network in Boston

Physicists demonstrate first metro-area quantum computer network in Boston It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what Harvard physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date. Think of it as a simple, closed internet between point A …
